Laches

What laches means

Put simply, laches is part of the working vocabulary of a civil case. The short definition above covers the usual meaning. Still, a specific rule, statute or contract can give it a narrower meaning. For that reason, check how it is used in your own documents.

Where laches comes up

For example, the term appears in these procedures:

• Affirmative Defenses (Fed. R. Civ. P. 8(c)): defenses that defeat or reduce a claim even if the plaintiff's allegations are true. Rule 8(c)(1) lists examples such as statute of limitations, res judicata, release, payment and waiver.

Read the source: Statute of limitations.

How to research the term

Start with the primary source. For example, if laches appears in a federal rule, read the rule itself and its official notes. After that, check your court’s local rules and any standing orders from the judge. In addition, search recent decisions from your own state or federal district. They show how courts read laches in practice. Because state rules often differ, our state procedures guide links to each state’s official rules. Above all, make sure the version you read is still in force.
